Abstract: Disclosed herein is a low pressure discharge lamp having a coating disposed upon at least a portion of inner lead-in wires, wherein the coating comprises refractory nanoparticles. Also disclosed herein, in particular, are fluorescent lamps having a coating disposed upon at least a portion of inner lead-in wires, the coating comprising refractory oxide nanoparticles having a median primary particle size of less than about 70 nm, with a thickness of from about 0.5 micrometer to about 10 micrometer. Disclosed advantages may include lessened end discoloration over the operational lifetime of the lamp, enhanced lumen maintenance, and inhibited mercury consumption.

Abstract: A method for providing a boron-lined neutron detector. The method includes providing a boron-containing material and providing water. The method includes mixing the boron-containing material into the water to create a water-based liquid mixture and providing a substrate of a cathode of the neutron detector. The method includes applying the water-based liquid mixture to the substrate of the cathode and removing water from the water-based liquid applied to the substrate to leave a boron-containing layer upon the substrate that is sensitive to neutron impingement. The step of providing a boron-containing material may be to provide the material to include B-10.

Abstract: A light source comprising a light emitting component comprised of a semiconductor material, at least one phosphor material, at least one UV reflecting material, and optionally, at least one silicone layer and at least one encapsulant, is provided. This light source provides safety to the user against UV exposure and protection to other components within the device that may degrade upon exposure to UV radiation. Furthermore, the UV reflecting material reflects unconverted UV light back into the phosphor layer where it is converted to visible light, resulting in increased output from the light source.

Abstract: A fluorescent lamp having no more than one layer inside the glass envelope, the one layer being a phosphor-containing layer which is at least 20 weight percent alumina. The phosphor-containing layer preferably comprises a rare earth triphosphor blend.

Abstract: The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an organic or inorganic metal mercury antioxidant in the lamp structure or in the test solution.
